Thomas Piketty's (2014) book, Capital in the 21st Century, follows in the tradition of the great classical economists, like Marx and Ricardo, in formulating general laws of capitalism to diagnose and predict the dynamics of inequality. We argue that general economic laws are unhelpful as a guide...

We combine data on trade, production, and input use to compute the value added content of trade for forty-two countries from 1970 to 2009. For the world, the ratio of value added to gross trade falls by ten to fifteen percentage points, with two-thirds of this decline in the last two decades....

We develop a property-rights model of the firm in which production entails a continuum of uniquely sequenced stages. In each stage, a final-good producer contracts with a distinct supplier for the procurement of a customized stage-specific component. Our model yields a sharp characterization for...

This paper examines the impact of government-sponsored venture capitalists (GVCs) on the success of enterprises. Using international enterprise-level data, we identify a surprising non-monotonicity in the effect of GVC on the likelihood of exit via initial public offerings (IPOs) or third party...

This paper makes two methodological contributions. First, it proposes a framework to decompose total production activities at the country, sector, or country-sector level, to different types, depending on whether they are for pure domestic demand, traditional international trade, simple GVC...

We combine data on trade, production, and input use to document changes in the value added content of trade between 1970 and 2009. The ratio of value-added to gross exports fell by roughly 10 percentage points worldwide. The ratio declined 20 percentage points in manufacturing, but rose in...

This paper investigates the relative performance of enterprises backed by government-sponsored venture capitalists and private venture capitalists. While previous studies focus mainly on investor returns, this paper focuses on a broader set of public policy objectives, including value-creation,...

This paper develops a simple framework for understanding the emergence of new organizational forms, such as socially responsible firms and social entrepreneurs, that embody the private sector's efforts to resolve problems that typically have been within the purview of government and traditional...

This paper studies localization of academic and industrial knowledge spillovers. Using data on U.S. Research and Development laboratories, that quantify spatial aspects of learning about universities and firms as well as their locations, I find that academic spillovers are more localized than...

How have labor market institutions and welfare-state transfers affected jobs and productivity in Western Europe, relative to industrialized Pacific Rim countries? Orthodox criticisms of European government institutions are right in some cases and wrong in others. Protectionist labor-market...
